This adaptation involves both context-awareness and interaction mechanisms that can be classified into active and passive. While active mechanisms have been fully explored in existing prototypes and systems, passive mechanisms and their implications need to be more deeply studied. In this work, we present some theoretical principles on passive interaction as well as their application to EMI$^{\\textrm{2}}$: an AmI architecture we are designing combining active and passive environment interaction via mobile devices.}, urldate = {2013-10-28TZ}, booktitle = {Proceedings of the 2nd {European} {Union} symposium on {Ambient} intelligence}, publisher = {ACM}, author = {V\xe1zquez, Juan Ignacio and L\xf3pez de Ipi\xf1a, Diego}, year = {2004}, keywords = {Ambient intelligence, pervasive computing}, pages = {71--74} }"]
